They Demoted Pluto - And Exposed How Dumb We Really Are

Pluto was a planet—until scientists held a vote and kicked it out. What else have we been hilariously wrong about? From medicine to space, here’s why certainty is overrated…

Pluto used to be our ninth planet—until it wasn’t.

In 2006, a group of scientists demoted it to “dwarf planet” status, and suddenly, everything we knew about the solar system got a little weirder.

But Pluto’s not the only thing we’ve misunderstood. We once thought smoking was healthy, that babies didn’t feel pain, and that doctors didn’t need to wash their hands. Oops.

This episode of An Ounce is a hilarious reminder that some of our “facts” might not be facts forever.
So the next time you hear someone say, “It’s settled science,”—you might want to smile politely… and leave the door open.
